Nimboid – adjective – Highly musclebound, of low intellect and prone to violence, often as the result of hormonal imbalance (see nimboidism).
My brother and I invented the word ‘nimboid’ as children after seeing a TV news article about the z-movie classic A Nymphoid Barbarian in Dinosaur Hell and mishearing the title. We didn’t necessarily formalise the definition, I just always figured – after assuming one of the musclebound freaks show in clips from the movie was the barbarian of the title – that this is what it meant.
